Title (EN) ROLLING BEARING
(FR) ROULEMENT
(JA) 転がり軸受
Abstract:
(EN) The invention addresses the problem of providing a solid lubricant type rolling bearing that can be suitably used under radiation exposure and under low-temperature, low-vacuum environments, such as in outer space. A rolling bearing (1) comprises: an inner ring (2) in which a raceway (4) is formed on the outer circumferential face; an outer ring (3) in which a raceway (5) is formed on the inner circumferential face; a plurality of rolling elements (6) that are embedded between the raceways (4, 5) of the inner ring (2) and the outer ring (3); and a cage (7) that retains the rolling elements (6) at intervals in the circumferential direction and that contains a solid lubricating agent. The primary component of the cage (7) is polyethylene.
(FR) L'invention a pour but de fournir un roulement du type à lubrifiant solide qui peut être utilisé de manière appropriée sous une exposition aux rayonnements et dans des environnement à basse température et à faible vide, tels que dans l'espace extra-atmosphérique. Pour atteindre ce but, l'invention concerne un roulement (1) qui comprend : une bague interne (2) dans laquelle une piste de roulement (4) est formée sur la surface périphérique externe ; une bague externe (3) dans laquelle une piste de roulement (5) est formée sur la face périphérique interne ; une pluralité d'éléments de roulement (6) qui sont incorporés entre les pistes de roulement (4, 5) de la bague interne (2) et de la bague externe (3) ; une cage (7) qui retient les éléments de roulement (6) à des intervalles dans la direction périphérique et qui contient un agent de lubrification solide. Le composant principal de la cage (7) est du polyéthylène.
(JA) 宙空間などの放射線性暴露下かつ低温低真空環境下で好適に使用される固体潤滑方式の転がり軸受を提供することを課題とする。外周面に軌道面(4)が形成された内輪(2)と、内周面に軌道面(5)が形成された外輪(3)と、前記内輪(2)と外輪(3)の軌道面(4,5)との間に組み込まれる複数の転動体(6)と、前記転動体(6)を円周方向に間隔をおいて保持し、固体潤滑剤を含有する保持器(7)とを備えた転がり軸受(1)において、前記保持器(7)は、ポリエチレンを主成分とする。
